WebThe data encryption standard, or DES, is an encryption algorithm that converts plaintext into blocks then uses a key to convert it to ciphertext. DES is based on an earlier cipher by cryptographer Horst Feistel, called Lucifer. Developed in the 1970s, Lucifer was one of the earliest block ciphers. WebData Encryption Standard is a symmetric-key algorithm for the encrypting the data. It comes under block cipher algorithm which follows Feistel structure. Here is the block diagram of Data Encryption Standard. Fig1: …

WebAug 17, 2024 · DES is a block cipher and encrypts data in blocks of size of 64 bits each, which means 64 bits of plain text go as the input to DES, … The Data Encryption Standard is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in the advancement of cryptography. Developed in the early 1970s at IBM and based on … See more The origins of DES date to 1972, when a National Bureau of Standards study of US government computer security identified a need for a government-wide standard for encrypting unclassified, sensitive information.
